Mach4 Spindle lag problems
« on: September 25, 2018, 06:09:36 AM »
Hi. I got a serious problem with my Mach4 Spindle.

Case:
Spindle are running, and 1 or more axis are moving But when all axis movement stops my spindle does an short halt. Not long, but I can see it on the spindle and
hear clicking noise from the servo spindle motor. If 2 axis are moving and 1 axis stops it's ok. It happens only when last axis stops. This happens both in manual
and G-code running mode. There is no difference whenether I move axis with external buttons or buttons onscreen.
I tested several orginal WX4 screensets, and are pretty sure this error must be in MAch4 Core or maybe some settings in my SmoothStepper ???

My machine setup are like this:

Mach4 (latest release)
ESS SmoothStepper
Pokeys 57U for external button panel
Spindle 1,8kw AC Servomotor
X and Y 750w AC Servomotor
Z 1,3kw AC Servomotor
A 200w AC Servomotor
PLC for lubrication, tool release and some safety stuff

Any suggestions anyone ? This is kinda gamebreaking.

My spindle does the same thing.  I'm running an AC motor with a VFD and not a servo, but none the less, after I jog it will sometimes wind down for a fraction of a second and wind back up.
Also running the ESS

I didn't have this problem when I first started using Mach4 on this mill.  Don't know what changed. 
I don't have this problem on any of my HiCON Integras.
